Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid.

About The third is community. We believe learning should be as rich and varied as the world you're learning about. So with our community we're building a kind of multimedia wonderland of learning, where videos, audio, usage, mnemonics, etymologies and much more bring your learning to life. We believe that every learner is partly a teacher, and we hope that once you get started, you'll soon be supplying little nuggets of wit and wisdom to help the rest of the community as they learn!

The term was coined in 2008 by David Cormier, manager of web communications and innovations at the University of Prince Edward Island. The first MOOC was created the previous year, at Utah State University. Today, there are hundreds of thousands of courses available online at no cost. You can study anything from business to zoology in your own home at no cost.
Ten Recent Advances in Evolution By Carl Zimmer Posted 10.26.09 NOVA To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself. Evolution Resources from the National Academies In the News: Your Inner Fish – A Scientific Adventure Have you ever wondered why people look the way they do? Why our hands and feet have five digits instead of six? Why we stand on two legs instead of four? It took 350 million years of evolution to produce the amazing machine we call the human body and in Your Inner Fish, a three-part series based on the best-selling book of the same name, author and evolutionary biologist Dr.
Fisher's exact test of independence - Handbook of Biological Statistics Summary Use the Fisher's exact test of independence when you have two nominal variables and you want to see whether the proportions of one variable are different depending on the value of the other variable. Use it when the sample size is small. When to use it Center for Health and the Global Environment Here are some simple ways you can work to protect biodiversity -- and human health! Making small changes in your food, your transportation, and your home can have significant impacts. Here's how:

Philosophy Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The Ancient Greek word philosophia was probably coined by Pythagoras and literally means "love of wisdom". In the 19th century, philosophy became more professionalized as it began to be studied and taught in modern research universities. Contemporary academic philosophers subdivide research areas in various ways. For example, topical divisions include major branches such as epistemology, logic, metaphysics, ethics, aesthetics, and other specialized branches. Other ways of dividing include historical period (e.g., ancient and modern); thinker (e.g., Platonism, Confucianism, Kantianism); or philosophical tradition (e.g., analytic or Continental).
Crystallized Icicle Ornaments with Borax Have you ever made “ice crystals” with Borax and Pipecleaners? It’s a classic science experiment for kids, but believe it or not, until last week, we hadn’t done it before. We decided to give it a try, and we made these Crystallized Icicle Ornaments, and I have to tell you, it I was really impressed!
